Specification of Letters Patent.

Patented July 9, 1907.

Application filed August 80.1906. serial No. 832,580.

To all whom it may concern:

Be it known that I, .Iosr': F. Fnnms, a citizen of the Republic ofMexico, and a resident of Monterey, Mexico, have invented a new andImproved Fiber-Gleam ing Machine, of which the following is a full,clear, and exact description. 7

This invention relates to improvements in machines for removing theouter covering and pulp of fibrous material such as sisal, palma,lechuguilla and analogous plants, the object being to provide a machinefor this purpose that will be simple in construction and by means ofwhich the work may be rapidly carried on.

I will describe a fiber cleaning machine embodying my invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar characters of reference indicatecorresponding parts in all the figures. I 1 5 Figure 1 is a plan of afiber cleaning machine embodying my invention; Fig. 2 is a sideelevation thereof; and Fig. 3 is an end elevation.

In the machine the material is first passed through a series of crushingrollers 1, driven by any suitable means and then deposited on ahorizontal plate or apron 2, from which the crushed material is manuallytransierred or pushed to the endless carrier 3, arranged at right anglesto the apron 2; the endless carrier takes the crushed leaves to thegripping or conveying chains 4, 5; these are two lower and two upperchains, ongaged alternatively and running on special sprockets 6,

lines of teeth and at one side of them serve as a bed for theintervening chains to rest on; the leaves are bent in the shape of an Swhen gripped. While the chains 4, 5, carry the leaves by one end, theother end passes through the cleaning device, consisting of a wheel 8,with adjustable scraping blades 9, on the surface, and a wire wheelbrush 10, next to it and mounted on the same shaft; the scraping bladesand circular brush work against a shield 19 of segmental or curvedfdrln, provided, on the back, with a means for adjusting same in orderto secure a perfect contact with the scraper and brush. When the leavespass out of the first scraper and brush, the clean ehd is grippedby asecond set oi gripping chains 13, 14, before the other end is free fromthe first gripping chains 4, 5; when that end is tree from the firstchains it passes through a second scraper wheel 12-, and circular brush1'1, acting against their corresponding segmental shield. The middleportion oi the leaves, cleaned by the first scraper and'brush is alsoorder to insure athorough cleaning of the whole length a main shaft 15,on which-is mounted a fast pulley 16,

and a loose pulley 17, these several parts being mounted in a frame 18.

In the operation, the fibrous leaves are carriedirom the crushingrollers endwise along the apron 2, and then pushed or transferredmanually to the endless carrier 3,- i'rom which they are fed between thefirst two pairs of gripping chains as above mentioned, and operated uponby the first scraping blades and brushes againstthe shield, which ofcourse only cleans the covering and pulp from one end. The leaves arethen carried, by their clean end, by the second two pairs of grippingchains to the second scraping blades and wire brushes to clean thecovering and pulp from the opposite end.

Having thus described my invention I claim as p ow and desire to secureby Letters Patent:

1. A device of the class described, comprislng crushlng mechanism.arcceiving apron, ah endless carrier running at riglitangles to theapron, a plurality of-conveying devices each of said devices comprisingupper and lower pairs of endless chains, the runs of one pair being inthe same plane with the adjacent runs of the other pair and arranged inalternation therewith, one of said conveying devices being arranged togrip material by one end. as it leaves the endless carrier, and theother of said devices being arranged to grasp the material by the otherend as it leave the first conveying device, and cleaning devices in thepath of the material conveyed by said conveying dc-- vices, saidcleaning devices each comprising a drum havinga portion of the peripherythereof provided with an annular series of crushingblades, and anotherportion provided with an annular brush.

A device of the class described comprising crushing mechanism, areceiving apron, an endless carrier lying at i'ig'lilang'lcs to theapron, a plurality of gripping or conveying devices, one of such devicesbeing arranged to grasp the material by one end as it leaves the endlesscarrier and the other of said devices being arranged to grasp thematerial by the other end as it leaves the first of said conveyingdevices, and cleaning devices in the path of the material conveyed bythe conveying devlces, each of said devices comprising a drum having, aportion of the pe ripbery thereof provided with an annular series ofcrushing; blades and another portion provided with an annular brush.

3. A device of the class described, comprising'crus'hlng mechanism, areceiving apron, an endless carrier running at rightanglcs to the apron.gripping or conveying chains comprising upper and lower pairs of endlesschains, the runs of one. pair being in the same plane with the adja--cent runs of {be other pair and arranged in alternation therewith, andchurning devices in the path of the mateinn :1 poi-lion of the peripherythereof pi'ovlded with an annular s ries of adjustable crushing blades,and the other \jrle with an annular brush.

in testimony whereof I have signed my mime to this 3]" vif'u-zition inthe presence of two subscribing witnesses. 7
